T0 .ALLWHOM I'l MAY CQNCERN:

Be it known that I, J. O. BELKNAP, of the city and county of Mobile, and State oi' Alabama, have invented a new and improved Device for Propelling Pleasure-Boats; and I do hereby declarevthat the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side elevation.

Figure 2 is a top view.

Figure 3 is a detached view of the upper end of the standard C.

This invention is a v neat and ornamental apparatus for moving pleasure-boats in' a circle around a. central standard, 4by means of horse-power. D l

In the drawings, A represents a circular or polygonal wharf, surrounded on all sides by water, and provided with a railing, B, around it. At the centre ofthe wharf rises a stout standard, C, having a pin or gudgeen, c, in its upper end. This standard supports a frame, consisting of two horizontal crossed beams, D D', which frame rotates freely in a horizontal plane upon the gudgeon-c.

The frame may be :fur-ther supported, and its'motion steadied, byrneans of rollers or casters, a a, attachedto its under side, and running upon a'cireular track. The track may be made in the form of a circular or annular platform, E, supported upon independent posts, or upon arms, c e', branching out from thc main standard, C. From the outer ends oi' the beams D D', sweeps, F F F2 F3, extend upward, then outward and downward nearlyto the surface ot`- the water, where the boats H H are attached to them by a rope, I, and are caused Wto sail around the wharf by means of horse-power, or other power, applied to the sweeps or to the frame D D', as

seen in iig. 2. A neat canopy, J, supported upon a frame, K K, which rests upon the frame D D', and is carried round with it, may be employed inv connection with the apparatus. The c'ent'ral pele of the fameK, shown at L, may extend up through the apex of the canopy, answering the purpose of a iag-staif.

The whole apparatus-can be erected and maintained at but little expense, and will forni an ornamental and` very desirable appurtcnancc to a gentlenians grounds. It will be far safer for the use of children than is Vthe ordinary sail-boat, and eanbc employed in all kinds of weather, operating as well in a calm as at any other time. Having thus described my invention, what I claim as new, and desire to secure by LettersPatent, is

. The employment of a revolving frame, working on a vertical standard, and having arms onsweeps, to which pleasure-boats may be attached, for the purpose et' propelling such boats on the water, substantially in theman-v ncr above set forth.V J o BELKNAP Witnesses: n u
